-- Talks. "Syria's opposition will not participate in proposed international peace talks in Geneva next month, its leader has said." That report from al-Jazeera adds that "George Sabra, the head of the Syrian National Coalition (SNC), on Thursday said the opposition was suspending their participation until the international community intervened to end the siege in Qusayr, a town in Homs province near the Lebanese border."

Meanwhile, according to Reuters, "Russian, U.S. and U.N. officials will meet next week to discuss ways to bring the warring sides in Syria together for a peace conference, Russian news agencies quoted a Foreign Ministry official as saying on Thursday.
